Six foot and ten foot rockets? Those are serious stuff!
Now, for our metric friends, where's that conversion thing? 1.8m and 3.0m. I don't know what the hardener would do to paper and glue, but on balsa nose cones it seems to continue hardening for about a year after application. (there are a bunch of unfinished LPR rockets in the closet, and a few finished or mostly finished on the wall) Aleen's will take lacquer just fine when I saturate paint assembled cardboard and/or pasteboard box models with it. Even though the hardener is different chemicals from lacquer, maybe that is a good sign?

Here is a link to a Air Howitzer Canon launcher that impresses me the most. https://www.flickr.com/photos/jurvetson/3972922344/ After checking the main photo read the comments and scroll down for another photo. These guys are launching at 1000 feet per second or around 682 mph. BTW-My rockets are just cardstock, with minimum parts to keep the weight down-no escape systems, or detail parts added. The 10ft tall Saturn V weighs less than 3lbs if I remember right. I do have some videos and photos of flying them. Here is a link to what I have here: http://www.papermodelers.com/forum/m...uers-projects/ Mike |

I REALLY like this! As a desktop model or as one of your stomp rockets, what a winner!

Everything Mike offers us is so different and interesting.
Paper Models? or pure brilliance? Another great project Mike. But I do have to say...not enough videos of these things in action. Many, like me, don't have the ability to get into this and since I live in a small City, I don't have many places to launch these type sof models. So, I experince it through your photos and videos. Give me more videos!! LOL What happened with the Pulsejet?

The pulsejet is morphing into the next stage. Hopefully the final one! Decided to go with an aluminum "power skid". Basically the engine, fuel tank and electronics mount inside the paper. Welded aluminum structure won't vibrate apart like the present wood structure can. Was thinking of making it slightly larger, however the present size is nice and light, plus everything fits. Still deciding on the size... One final addition will be "dolly" that it rides on for takeoff. Once it is airborne the dolly drops off just like the Me163. Waiting on my new AC/DC Tig/Stick welder to get here. Local high school has a welding program, they also have a really cool plasma table. The instructor will cut my parts if I give him a .dxf file of the shape I need for the internal skid. Once cut plan to do the welding here at home. In other words, probably sometime next winter before a working/flyable version is ready for the one test flight. BTW- recently purchased a great video camcorder from canon. Next rocket launch videos will have sound and a great HD view. Just not sure when the next launch day will be. I do have a new recovery system planned to deploy a parachute. It will be tested when I fly a full size ARCAS rocket (air pressure powered). Mike |

Any progress on the downscale?

Just finished working on graphic issues, next will be another test build to verify graphic changes work. Then downsize will be done.

Just a suggestion here...allow enough room in the tail section to put a moter mount for Micro Maxx sized engines. If it's not a large redesign issue on your end. At 18-25 ft max altitude, tumble recovery wouldn't do any damage to the model.
And it would keep your design flying! |

I'll see what happens if I downsize the internal PSI tube at a size it could fit in. This could cause build issues as the model has been designed to barely fit the internal PSI tube-interesting build trying to get fuselage sections together. It does have a removable nose-cone. Planning to keep the downsize to be printable on letter without chopping wings, or fuselage up a bunch. If it will work for the engine I'll do it. Mike |
